mn eu n fled ma 1, 1908. serial are. 435,974.

of the cialyl of New. York, borough of Brook 1 l in e county of Kingsand Stateof ew York have invented a new and Im proved LubricatingAttachment for Wind-- in -Machines, of which the following is a jmer ofwhich is threaded and the latter of fu l, clear, and exact description.

This invention relates to certain im rove- I r m- ,wax, or-ot ersimilarma e like, as the, latter is being wound onto a spool, bobbin,-

ments in ap lying a lubricant, as, stance, para I terial, to yarn,thread, or

or spindle.

Various winding machine, as, for instance, while passing from a skein toa bobbin. The applying of the lubricant to a single thread or stranpresents certain diflicu ties, in that if sufficient pressure be appliedto the thread -vation of the to lubricate it to the eslred extent, thethread isoften broken, or if there is a knot or enlargement in thethread, the thread will break when said knot or enlargement comes incontact with the lubricant.

The object of my invention is to apply the lubricant tothe thread afterit is wound on the bobbin or the like, the lubricant pref-' erably beingin solid form and held against the sides of the several windings on the.

bobbin as the latterrotates.

Reference is who had to the accompany-f forming apart of thiss ofmechanism constructed in accordance with my invention, and Fig.2 is aside eleparts shown in Fig. 1, the spindle or bobbm bein removed.

My invention is ap lcable for use in any type of winding mac e, and thelubricant may be held a inst the material while wound on a bob in,spindle, spool, or any other rotatable member; the materlal to belubricated may be yarn, or thread of cotton, wool, or any othermaterial.

In the accompanying drawings, I have shown a portion of'a common type ofmachine for winding yarn from skems to the bottle bobbin used onknitting machines.

The bobbin 10 is-mounted for rotation and difierent mechanisms have.been designed and employed for lubricating a single strand of yarn orthread while in a portion-of my 3 In connection with this winding 1 isadapted to receive .yarn thereom 'Ad ,jacent the bobbin, there ismounted a base or. platform 11, vertically movable under the action of acam or any other suitable mech and upon platform is mounted a sm .fildeand the controlling means therefor . of machine, the platform .11carries two uprights 12 and 13, the forwhich is smooth. Mounted on thethreaded upright 12 is a cone 14 having a thin bar At the lower end ofthe cone and rotatable in respect thereto, is a collar 17 having twoarms 18 and 19. The arm 18 terminates in a sleeve encircling the upr' ht13 and serves to preventthe rotation of t e arm 18 about ht 12, so thatas the upr' ht 12, and the-arm 1-9 carries a yarn gui e 20 adjustable inrespect thereto. he entire mechanism'mounted on the base 11 is moved upand down, so that the ide 20 is moved ongitudinally of the b0 bin.

When the yarn hasiaccumulated onthe lower end of the bobbin to such anextent that. it contacts the conei the latter is rotated-to travel u theupright 12' and rais'e'th'e. 'de. old-and t e details thereofconstituten invention.

. mechanism, I employ an attachment for applging a lubricant, preferablyarafiin, to t e yarn as it is wound upon e bobbin. In

' of this mechanism is the specific form shown, this attachment"comprises an arm 21 mounted to swing on the upright 13 and disposedabove the arm '18, so as. to be moved upward when the cone 14 is rotatedto raise the arms 18 and 19.

At the outer end of the arm 21 is a suitable down and the entire outersurface each layer of yarn on the bobbin is thoroughly and eflectivelycoated with the lubricant.

. The lubricant may be held against the bobbin with any desired amountof pressure, and it will not tend to break the yarn or be interferedwith by the passage of a knot, en-Z largement or other obstruction inthe yarn. By holding the lubricant against the yarn on'the bobbin, theyarn passes it several times before being covered by" a second layer ofyarn. The lubricant'serves to hold the yarn in place on the bobbin, andserves to a certain extent to guide or direct it. When a single strandof yarn is drawn ast the lubricant, a difference in the s ee I ofwinding at the be ning and the en of the bobbin, makes a lubrication,but the lubrication is uniform when the lubricant is held against thebobbin as in my construction.v

Various changes may be made in the construction and details of thelubricating attachment, and it may beapplied to various diflerent ty esof .machines.

In the 0 owing-claims, the term yarn is used to cover any and all formsof threads or strands, irrespective of the material, and the term bobbinis used-to designate any type of rotary member upon which any type of amis to be wou'nd.

liaving thus described my invention, I

ifl'erence in the degree of new claim as new and desire to secure by Letters Patent:

1. In a winding machine, the combination of arotatable member upon whichthe yarn is to be wound, and means movable longitudinally of therotatable member for re- ,siliently holding a lubricant against thewound ya'rn on said member, said means includin a U-shaped bar of springmetal, the terminal portions of which form sprin jaws for engaging withopposite sides 0 the lubricant and a clamping bolt extending throughboth of said jaws at a distance from the end thereof for moving themrelatively to each other.

2.- In a winding machine, the combination of'a rotatable member uponwhich the yarn is to be wound, a guide movable longitudinally of saidmember for directing the yarnthereto, and means movable lon itudinall ofthe rotatable member and wit said gui e for holding a lubricant againstsaid yarn after it is wound on said member, said holding means includintwo spring-pressed jaws having inwardly-directed teeth and a clampingbolt for drawing said jaws together.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

'SELIG BROADWIN.
